i ve started UART pgm in PL3200 which has 8051 embedded inside. it has serial ports and RS485A & B pin and port 3 has infrared too.which port shall i choose for uart communication. and plz guide me how to start??
which port shall i choose for uart communication. either both will (as far as I can guess from what you post) do "UART communication" so choose the port for which the line levels is what you need.
i guess that this is an issue of language, you need to be more specific what do you want to communicate with?
